    I started up Postfix via 'sudo postfix start' and I can telnet into port 25 of 127.0.0.1 fine, but when I do I just get:
    Code:
    $ telnet 127.0.0.1 25
    Trying 127.0.0.1...
    Connected to localhost.
    Escape character is '^]'.
    HELO there
    
    I get no response or 220 welcome acknowledgment that the SMTP server is running?

    I get

    Code:
    Shrike: ~] telnet 127.0.0.1 25
    Trying 127.0.0.1...
    Connected to localhost.
    Escape character is '^]'.
    220 Shrike.local ESMTP Postfix
    
    This is on 10.6.4, without changing any of the postfix configuration files.

    After entering the telnet command, open a second Terminal shell (Terminal->Shell->New Window) and enter the top command. Do you see smtpd in the COMMAND column?

    Did you try sending a test email from your telnet session? Is the "HELO there" in your original post something you entered, or part of the response from the telnet command?
